Constant acceleration, bike vs. car

[QUOTE="Feodalherren, post: 4490200, member: 424891"] [h2]Homework Statement [/h2] Vroom, vroom! As soon as a traffic light turns green, a car speeds up from rest to 50.0 mi/h with constant acceleration 9.00 mi/h + s. In the adjoining bike lane, a cyclist speeds up from rest to 20.0 mi/h with constant acceleration 13.0 mi/h + s. Each vehicle maintains constant velocity after reaching its cruising speed. (a) For what time interval is the bicycle ahead of the car? (b) By what maximum distance does the bicycle lead the car? Doing part a. [h2]Homework Equations[/h2] [h2]The Attempt at a Solution[/h2] So my reasoning was that I need the position functions. I found them. I found the time at which the bike reaches its maximum velocity and selected that to be t=0. I adjusted both of the positions functions to this new setting. Then I just went to solve for at what t they meet and my plan was just to add the (20/13) to that t and I would have the time at which the car overtakes the bike. However, I'm not successful in getting the right answer. Where am I going wrong? Picture of my homework posted below. [SPOILER][ATTACH=full]163678[/ATTACH][/SPOILER] [/QUOTE]
